Open channel flow integrating instrument is a universal industry intelligent instrument. 4-20mA,0-20mA,1-5V and 0-5V linear signal output and RS485 serial output are optional. Integrating 2 line control module of signal input, this instrument separately control each line signal and do relative operating to display and output. Processing open channel flow integrating instrument function, it can be used as open channel flow meter. For flash disk to download data, it is flexible to use.
High precise, non-touching level measurement. Without an impact on flow velocity.
Low sensor power consumption, easy installation, and orientation, application wildly.
Widely used in wall hanging right-angle rectangular weir, triangular weir, Parshall flume and so on.
Easy operation, no need to calibration the input signal, only a few parameters should be set.
Full functions, 2 line relays output, easy to connect the actuating mechanism.
Flow integrating instruments possess data storage. Data can be also saved by the SD card.
According to condition,sensor can choose anti-erosion, anti-explosion, small blind area,ultra low power consumption or wild range
Base on user’s demand,it can attach flash disk、micro printer and storage battery .onic flow meter
